Re: Concern with my Spindle
Thanks Robert, I actually downloaded that and follows the procedure for preloading the Timkens.? That is where I remembered seeing the 0.002" value.? I don't remember if I checked for any lateral play at time of rebuild. -Jody

Sent from my T-Mobile 4G LTE Device -------- Original message -------- Date: 1/23/19 07:19 (GMT-06:00) Subject: [atlas-craftsman IO] Concern with my Spindle The last few times I've used the lathe, I put oil in the spindle cups and each have a flat piece of felt as? a wick laid in there.? Every time I put oil in them, the back oil cup is empty and the front cup is still practically full. It is probably the sealing of the metal caps that cover the front and backside of the? Timken Brgs.
Should this concern me?
I'll try taking the wick out of the front and see if that speeds up the oil usage but the back seems to be emptying too fast IMO.
When I rebuilt it I followed the procedures for setting the spindle and I seem to remember? the spindle should have about a 0.001 or so of play when cold.
I'm getting over 0.001, maybe 0.001-0.002 when i pull sideways on the chuck.?
Does this seem OK?
My work is coming out nice and I think the force I'm putting on the chuck to get that deflection is higher than a cutting force on most stuff.
Just checking to see if I need to adjust something or if anybody has had similar situations.
Thanks,

I’m several days behind and trying to catch up, so if someone already answered this, just disregard. ? Short answer is yes.? The Atlas 612 and 618 and the Craftsman 101.21400 have Timken tapered roller bearings on the spindle, and the spindle nose threads are 1”-10.? Craftsman 101.07300 has Oilite bushings and the nose threads are 3/4”-16.? Craftsman 101.07301 has Oilite bushings and the nose threads are 1”-8. ? All of the models have a single spring-loaded cover oil cup in the top of the casting over the bearings.? I think all are the same part number. ? The ones with bushings have a horizontal slit cut from the front of the part of the headstock casting that holds the bushings through to the inside of the hole that the bushing fits into.? And they have a single vertical clamping screw with a slotted Fillister head.? This area is solid on the ones with Timken bearings and there are no screws. ? Robert Downs ?

Subject: [atlas-craftsman IO] new guy - old 618? Hello everyone!
I picked up an old Atlas and have finally got around to messing with it.
I got the bed and all the ways on the compound, cross-slide, and suck nice with some kroil and a dish scrubby pad
I got most everything freed up and turning nice (spindle turned when I found it and seems nice and tight)
With a little luck, and some friendly advice, I may get this thing making chips before too long!
I do have some questions about these old six inch lathes.
I've read conflicting information on spindle bearing types, I understand the first craftsmans had a small spindle, besides that, is it correct that the 8TPI spindles are sleeve and the 10TPI are timken? That's mostly what I've read, mine has 10TPI and two little oil cups with spring loaded covers over the bearings.
Also I'm having trouble removing the gear from the leadscrew. It had a bolt and two washers in the end of it, removing it exposes the shaft and what looks like two woodruff keys? does it just need a little more time in the oil? I have removed the leadscrew. The left leadscrew bearing, though there's nothing stopping it, gets extremely tight if I move it as much as 1/16-1/8 of an inch to the right, I don't want to force it that way but I want it out or at least off the journal to clean.
Thanks to anyone who reads this, more so to anyone who is able to help.

My left oil cup actually empties faster than the right as well after looking due to this discussion. Why? A minute or two ago I pulled the felts out, I believe they're original. It's all spotless and I can't fill the cups as fast as it drains with them removed, left or right. No blockage. Plenty of leakage though, oil is cheap compared to parts!

I seriously doubt that how well the dust covers seal around the spindle has anything to do with oil flow rate.?

I have suspected for years that that is the reason for the large imbalance on my 3996.? ? Are the felts in your oil cups factory or not?? If not, then none of us have any basis for comparison.? I don’t mean to imply that there is automatically something wrong in using locally procured felt.? Just that there would be no basis for comparison. ? Robert Downs ? ? … ? I'm guessing the oil loss differential from the front to back bearings has to do with the metal dust caps sealing better on one end.

None that I have ever come across.? Definitely none that said anything about using the one screw in each clamp(that seems to be as good a term as any) to adjust the running clearance.? One should I think keep in mind that the headstock is made of cast iron, not steel.? Many steel alloys will cold bend at least a little.? Cast iron will break before it bends much. ? The 101.07301 went out of production in 1957.? The various factory Technical Bulletins with some more details on the care and feeding mostly seem to be dated later than that.? And although some apply to the Atlas 10” which went out of production at about the same time, I’ve never seen any specifically on the 101.07301.? Which is unfortunate. ? On the subject of drilling holes in the Oilite bushings, if you are going to do that, you will obviously increase the oil flow rate and to my way of thinking, may as well use the usually cheaper brass bushings. ? The only reasons that I could think of to explain faster emptying of the left cup than the right one on a 101.07301 is that the bushing is thinner or the inner surface of the right one has plugged up from wear. ?

Subject: Re: [atlas-craftsman IO] Welcome to [email protected]? The bearings as Robert points out do not have shims nor is there a "cap" there is however more what could be described as a clamp (see photo, chuck side is the same). This clamp (please correct me if you know the proper name) can be tightened but with great caution as the clamps can brake/crack. Tightening will remove some of the slop in the spindle, I would not use more than a firm hand on a screw driver to be safe. Also see a photo of the replacement bearings with no "holes".
Robert, is there any known specifications for tightening the bearing clamps, inch pounds, number of turns... or ?

Experience, was Re: Feed rate increase and crazy thread milling, just for fun
IF I ever actually get around to the point where I can start building the things I dream about, I'm probably going to use a 2x4 for the stock. As far as woodworking goes I'm a wood butcher. Or a rough carpenter. VERY rough.?
That is a beautiful piece of work. I am not anywhere close to being that skilled yet. Did get some good news last week. Wife does not have breast cancer. She does have a weird infection, and the antibiotic to treat it has a long list of scary side-effects. She's delaying taking it for now. But I have official permission to go back to class this week. Lord willing and the creek don't rise, I'll be back in class tomorrow. Thinking about making some stuff for my shop among the class projects. Tripped over a website this morning that has a free machine shop course, and project drawing to make several useful tools. Downloaded the drawings and shop notes.?
http://www.thatlazymachinist.com/
Should have been working on house and shop, but it's been a crazy week, and I had to make up missed time at work so didn't get a weekend and did really scramble my sleep schedule. Almost time to go back to sleep so I have 8 hours of sleep before I go to work tonight.?
Need to do a few things for her, and a few for my shop, and make sure I'm ready for work tonight.?
Y'all have fun!
Bill in OKC?

Re: Concern with my Spindle
I seriously doubt that how well the dust covers seal around the spindle has anything to do with oil flow rate.? In the first place, the dust covers don’t come anywhere close to actually sealing to the spindle.? However, they could be blocking the hole in the top of the headstock.? I have suspected for years that that is the reason for the large imbalance on my 3996.? ? Are the felts in your oil cups factory or not?? If not, then none of us have any basis for comparison.? I don’t mean to imply that there is automatically something wrong in using locally procured felt.? Just that there would be no basis for comparison. ? Robert Downs ?

Subject: Re: [atlas-craftsman IO] Concern with my Spindle? … ? I'm guessing the oil loss differential from the front to back bearings has to do with the metal dust caps sealing better on one end.
I'm curious if other's oil cups are empty on the spindle each time they use it?
Thanks,
Jody

Ken – you are welcome
The question comes up from time to time so I thought it might be of interest . . .
“High Speed” is relative . . .? I must admit I seldom seem to run the lathe above 600 rpm for small – medium machining tasks in metal , except maybe for the odd drilling job with small drills . . .?
Keep well, ? Carvel ?
